The two terminal treads have their adjacent ends free from a hinge in order that the protector can be opened to apply the same to the tire, it being essential that the treads, as well as the associated sections 6 be united, and in order to accomplish this a turnbuckle 19 is employed, one upon each side, the bolts 20 thereot' being engaged in the plates 21 fixed to the treads S, as shown in Figure 5, there being straps Q2 connecting the barrel 23 of the turnbuckles with the adjacent sections (3 to prevent accidental rotation of the turn buckles.

The ribs 11 are formed with a plurality of perforations 24 to permit ventilation.

In Figures 6 and 7 there is illustrated a modified form of the invention which lor use in connection with truck or bus wheels employing a pair of tires 25 upon each rear wheel. In this form of the invention a pair of sections 26 are employed, one for each tire. said sections being connected to the treads 27 by brackets 28, as in the preferred form of the invention. Trucks and buses usually employ disk wheels and the rim 2) of the disk wheel is illustrated in Figure 6, the treads 27 being secured thereto by bolts 30 confined in the spacing sleeves 31. The treads are provided with a pair of tire engaging ribs and in which are seated cleats 33 which may bi arranged at any desired angle thereon. and may be of any preferred design.

In Figure 8, another modified form of the invention, the sections have notches 3.3 in their adjacent ends for engagement with the rubber lugs 36 carried by the tire. said lugs serving to prevent creeping ot the pro tector upon the tire and being used in lieu of the straps 17 of the preferred form of the invention. Treads 38 are secured to the sections 31 as in the preferred form of the invention.

In Figure 9 the treads 39 have bars it) connected thereto and provided with plates 41 which rest upon the sides of the tire 4'2 and are maintained in place. by rods 4-3 which have their respective ends secured to the treads and telly 44.

In Figure 10 a tread is designated by He numeral 45 and upon which is engaged a rubber tread -16 having side flanges 46' for engaging the sides of the tread the tread 46 being retained on the tread 45 by bolts 47 which are engaged in sockets 48 of the tread 45. These sockets are also employed for securing the cleats when the tread -16 is not in use. The cleats are obviously removed from the treads and the tread 46 secured thereon. The tread 46 is primarily designed for use on city pavements where cleats are prohibited. It will be of course understood that under normal conditions the cleats will not he used, but since they are detachable and can be readily applied when desired they will add to the etliciency of the wheels. \Vhen the cleats are not used the protector is in the form of a continuous steel tire and will be comparatively smooth and can be used on pavements without injury thereto. Further, it will be observed that by using the treads 8, which are con'iparatively wide. that a vehicle equipped with the protector can be successfully propelled over soft or muddy ground.

Having thus described the invention, I claim:

A tire protector comprising a plurality of hingedly connected tread sections curved longitudinally and straight transversely, a like number of: tire engaging sections curved both longitudinally and transversely brackets between the marginal longitudinal edge portions of the tread and tire engaging sections and forming positive and brace connecting means therebetween, ribs between the middle portions of the tread and tire engaging sections. and cleats passing through the tread sections and secured in the said ribs.

In testimony whereof I atlix my signature.
